James E. Hansen

From SourceWatch

Dr. James E. Hansen, longtime director of NASA's Goddard Institute for Space Studies, said in a January 29, 2006, New York Times interview that officials at NASA headquarters had ordered the public affairs staff to review his coming lectures, papers, and postings on the Goddard Web site and requests for interviews from journalists.

"Since 1988, he has been issuing public warnings about the long-term threat from heat-trapping emissions, dominated by carbon dioxide, that are an unavoidable byproduct of burning coal, oil and other fossil fuels." [1]

Bio

According to his NASA GISS biography: "Dr. James Hansen heads the NASA Institute for Space Studies in New York City, which is a division of Goddard Space Flight Center's (Greenbelt, MD), Earth Sciences Directorate. He was trained in physics and astronomy in the space science program of Dr. James Van Allen at the University of Iowa. His early research on the properties of clouds of Venus led to their identification as sulfuric acid. Since the late 1970s, he has worked on studies and computer simulations of the Earth's climate, for the purpose of understanding the human impact on global climate. Dr. Hansen is best known for his testimony on climate change to congressional committees in the 1980s that helped raise broad awareness of the global warming issue. Dr. Hansen was elected to the National Academy of Sciences in 1995 and he received the prestigious Heinz Environment Award for his research on global warming in 2001."

Hansen's advocacy of coal moratorium and rapid phaseout

Hansen has recommended that no further coal plants be built that do not capture their carbon dioxide emissions, and has further recommended that all coal emissions be phased out by 2025 in the developed world and by 2030 in the developing world.^[3] According to Hansen, the consequence of emissions continuing beyond that time is increasing risk of passing "tipping points" and "points of no return."^[4]

"Changes such as the melting of the Arctic ice cap, the acidification of the oceans and the global rises in temperature could be approaching the point of becoming irreversible. In the face of such threats it is madness to propose a new generation of power plants based on burning coal, which is the dirtiest and most polluting of all the fossil fuels. We need a moratorium on the construction of coal-fired power plants and we must phase out the existing ones within two decades," he told the Sunday Times.^[5]

Hansen's reasoning for making coal the highest priority for the movement to prevent global warming is as follows:^[6]

At 385 parts per million (ppm), the increased concentration of carbon dioxide in the air today is primarily due to the burning of fossil fuels--coal, oil, and natural gas. In "Implication of 'Peak Oil' for Atmospheric Carbon Dioxide and Climate" PDF, NASA research scientist Pushker Kharecha and I show that proven and estimated reserves of oil and gas, used at any feasible rate, would at most take atmospheric carbon dioxide levels to 450 ppm--a threshold level that, if exceeded, will cause dangerous climate change. Coal reserves, however, contain much more stored carbon, and if used in power plants without carbon capture technology, have the potential to at least double the preindustrial atmospheric carbon dioxide amount of 280 ppm.

Most of the carbon dioxide from oil and gas usage is emitted by small sources (i.e., vehicle tailpipes) where it's impractical to capture it. Nor does it seem likely that Saudi Arabia, Russia, the United States, and other major oil producers will decide to leave their oil in the ground. Therefore, the only practical way to prevent carbon dioxide levels from exceeding 450 ppm is to phase out coal power except at plants where carbon emissions are captured and stored.

Hansen's recommendation consists of two parts:

• Moratorium on new non-sequestering plants.
• Phase-out of existing plants.

The first recommendation, a coal moratorium, has been the subject of widespread citizen organizing, state-level legislation, and proposed national legislation.

The second recommendation, a phase-out of existing plants, has received less attention. To date, no scenarios have been published recommending specific steps to implement the recommendation of a coal plant phase-out in the timeframe recommended by Hansen.

Several scenarios outlining a reduction in coal usage, generally targetted at a later date than recommended by Hansen, have been published.

In an interview broadcast on Radio Four’s Today programme Hansen described the proposed Kingsnorth power station in the UK as "a terrible idea. One power plant with a lifetime of several decades will destroy the efforts of millions of citizens to reduce their emissions".^[7]
